Question 1
At Alderbrook Financial Services, the FortiGate 7.6 security administration team encounters the following authorized operational case: a newly deployed FortiGate accepts administrator logins from every routable subnet despite a dedicated management network. They need a defensible FortiOS configuration, diagnosis, validation or prevention decision. Which FortiOS 7.6 administration action best addresses this incident?
Explanation
Correct Answer
Restrict administrative trusted hosts to approved management sources and remove unneeded remote access. This targets admin trusted-host restriction: administrative interfaces exposed to broad sources enlarge the login attack surface even when passwords are strong. After applying the change, verify that a login from the management subnet succeeds while an unapproved source cannot reach the admin service. The Alderbrook Financial Services case requires these specific FortiOS 7.6 conditions, not an unrelated permit or platform change.
Incorrect Answers
Authorize and register the correct device serial number in FortiAnalyzer under the proper management scope is a relevant remedy for a DIFFERENT problem—fortianalyzer device authorization—when a newly added FortiGate sends connection attempts to FortiAnalyzer but is absent from the authorized device list. In this Alderbrook Financial Services case that is not the failing component. Here the correct intervention is to restrict administrative trusted hosts to approved management sources and remove unneeded remote access because administrative interfaces exposed to broad sources enlarge the login attack surface even when passwords are strong.
Restore redundant dedicated HA heartbeat connections and check compatible cluster settings is a relevant remedy for a DIFFERENT problem—fgcp ha heartbeat cabling—when two FortiGates configured as a cluster both appear active after a heartbeat link fails. In this Alderbrook Financial Services case that is not the failing component. Here the correct intervention is to restrict administrative trusted hosts to approved management sources and remove unneeded remote access because administrative interfaces exposed to broad sources enlarge the login attack surface even when passwords are strong.
Use suitable path-level link-monitor or routing health checks in addition to physical HA interface monitoring is a relevant remedy for a DIFFERENT problem—ha wan health probe design—when upstream carrier failure beyond the Ethernet link does not trigger recovery in a FortiGate active-passive pair. In this Alderbrook Financial Services case that is not the failing component. Here the correct intervention is to restrict administrative trusted hosts to approved management sources and remove unneeded remote access because administrative interfaces exposed to broad sources enlarge the login attack surface even when passwords are strong.
